I want to import images into matlab workspace, they should contain positive integers and zeros. If I use imread(), they will be all zeros.

Wenyi - can you attach one of these images so that we can take a look at it? Or describe the images - what type are they? What is the integer type (8-bit, 16-bit, etc.)?

I definitely don't get all zeros with imread. Problem solved?
>> nnz(imread('C0039_100122_INDS.png'))
ans =
4624
>> nnz(imread('C0039_101785_INDS.png'))
ans =
12177

images_data = cell(1500,1);
for S = 1:size(want_files,1)
images_data{S,1} = imread(pngFile_names{want_files(S,1),1}); %load image data from 1500 matched files
end
this is the code I used.
